Item Open Access Evaluation of flavored mono-sodium glutamate in swine starter rations(Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-05-07T21:40:38Z) Allee, G.L.; Hines, Robert H.Suckling pigs (2 to 4 weeks old) offered a choice of diets containing either flavored or unflavored mono-sodium glutamate (F-MSG or MSG) consumed 3.5 times more of the flavored than of the unflavored diet. Likewise, litters of suckling pigs offered only F-MSG diets consumed 3.5 times more than litters offered only the MSG diet. After weaning, pigs with access to F-MSG during the pre-weaning phase exhibited an initial and continued preference for the F-MSG diet by consuming 3.8 times more of it than of the MSG diet in preference trials. Pre-weaning feeding of pigs altered initial post-weaned preference patterns, as pigs with access to only the MSG diet did not prefer the F-MSG ration until the second week of the preference trial. In the second experiment, weaned pigs fed a flavored starter diet (flavor only) consumed significantly more feed per day and gained significantly faster than pigs fed either the F-MSG or MSG diets used in experiment I. Pigs fed the flavored ration consumed more feed per day than pigs fed the unflavored ration, but not significantly more. The feed:gain ratio of all treatments; flavor, F-MSG, MSG, and basal diet were similar.Item Open Access Evaluation of a wheat protein concentrate for finishing swine(Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-05-07T21:40:25Z) Allee, G.L.; Deyoe, C.W.; Hines, Robert H.Two experiments involving 66 finishing pigs were conducted to determine the feeding value of a wheat protein concentrate. Pigs fed diets containing as much as 60% wheat protein concentrate consumed the same quantity of feed, gained at the same rate, and were just as efficient in feed utilization as pigs fed the control diet. Pigs fed the diet containing 96.1% wheat protein concentrate consumed less feed and gained significantly slower (P<.05) than pigs fed the control diet. Extrusion processing of the wheat protein concentrate gave no beneficial effect on feed intake, daily gain or feed required per unit of gain. It appears that up to 60% wheat protein concentrate may be used in finishing pig diets with no adverse effects.Item Open Access Supplemental copper for growing-finishing swine(Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-05-07T21:40:11Z) Allee, G.L.; Hines, Robert H.One hundred forty-four pigs averaging 61 pounds were used to determine the influence of copper level on performance, copper storage in the liver, and to determine the influence of withdrawing during the finishing phase. Pigs fed 125, 187, or 250 ppm copper gained significantly faster (P<.05) than those on the basal diet containing no copper. Responses to copper and to an antibiotic were similar. Most of the growth response from the added copper occurred during the first 8 weeks of the experiment. Withdrawing copper the latter part of the finishing phase influenced neither gain nor efficiency of feed conversion but significantly (P<.05) reduced copper stored in the liver.Item Open Access Fortified milo for gestating sows(Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-05-07T21:39:58Z) Allee, G.L.; Koch, B.A.; Hines, Robert H.Forty sows (Yorkshire, Hampshire, and Duroc) were used to study effects of feeding a milo diet fortified with vitamins and minerals (FM) to bred sows from approximately 25 days after breeding to 10 days before farrowing. The sows were fed in this manner for three gestation periods. Control sows received a balanced milo-soybean meal diet (MSB) throughout gestation.Item Open Access High-moisture, acid-treated grain for finishing swine(Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-05-07T21:39:29Z) Allee, G.L.; Deyoe, C.W.; Hines, Robert H.The feeding value of high-moisture milo treated with organic acids for finishing swine was studied in two trials involving 56 pigs. There were no significant differences in daily gain, feed intake, feed efficiency, or carcass measurements between pigs fed the dry grain and those fed the high-moisture grain treated with organic acids. Preserving milo with organic acids apparently has no detrimental effect on performance or carcass merit when fed to finishing pigs.Item Open Access Nutritional value of triticale for growing swine(Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-05-07T21:31:16Z) Allee, G.L.; Hines, Robert H.One hundred thirty-five pigs averaging 57 pounds were used to determine the feeding value of triticale and the influence of physical form (meal or pellet) on the performance of growing pigs. Triticale replaced 20, 40, 60, 80, or 100% of the milo in a 16.5% crude protein, milo-soybean diet. Level of triticale had no significant effect on feed intake, daily gain, or feed:gain ratio. Pigs fed triticale supplemented with soybean meal (isonitrogenous with control) and the pigs fed triticale supplemented with 0.2% L-lysine gained significantly (P <.05) slower than pigs fed the control diet. Physical form (meal or pellet) had no significant effect on feed intake, daily gain, or feed:gain ratio. The results indicate that triticale can be substituted on a weight basis in diets for growing pigs but not on a protein basis.Item Open Access Muscling selection in swine and its effect on carcass traits(Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-05-07T21:30:38Z) Wheat, J.D.; Kropf, Donald H.; Hines, Robert H.We are attempting to develop a well-muscled line of Durocs by selecting for minimum back fat and maximum loin eye area as estimated by the Anscan and to form a control line by randomly selecting from the same base population. The lines will be compared for performance and carcass traits, including incidence of pale soft exudative carcasses. Expected and realized heritability estimates for carcass traits will be calculated.Item Open Access Influence of fat level and calorie:protein ratio on performance and carcass composition of young pigs(Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-05-07T21:30:27Z) Allee, G.L.; Hines, Robert H.One hundred forty pigs averaging 28 pounds were fed a corn-soybean meal diet to study the influence of fat level and calorie:protein (C:P) ratio on the performance and carcass composition. With a constant C:P ratio, fat level made no significant difference on daily gains, but feed efficiency improved as fat level increased. Increasing fat without adjusting the C:P ratio decreased daily gain and metabolizable energy per unit of gain increased. With a constant C:P ratio, feeding 6 or 12% fat did not influence fat content of the carcass. However, feeding 12% added fat without adjusting the C:P ratio markedly increased fat content of the carcass.Item Open Access Nutritional adequacy of triticale for finishing swine(Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-05-07T21:30:16Z) Allee, G.L.; Hines, Robert H.An experiment involving 81 finishing pigs was conducted to determine the nutritional adequacy of triticale for finishing swine. Pigs fed triticale alone gained significantly (P<.05) slower than pigs fed any other diets. Adding 0.1% L-lysine to triticale significantly (P<.05) increased daily gain. There were no significant differences in daily gain, feed intake, or feed:gain ratio between pigs fed triticale + lysine, triticale + soybean meal, milo + soybean meal or wheat + soybean meal. Differences in backfat thickness, loin-eye area, length or percentage of lean cuts in the carcass were not significant. Lysine is the first limiting amino acid in triticale for finishing swine. The lysine in triticale may not be totally available to pigs.Item Open Access Flaked corn, wheat, and sorghum grain for growing pigs(Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-05-07T21:30:04Z) Allee, G.L.; Hines, Robert H.One hundred fifty-three barrows and gilts were used to evaluate flaking of corn, wheat, and sorghum grain for weaned pigs. Flaking increased rate of gain and improved feed efficiency (9 to 10%). Pigs fed corn rations gained significantly faster and were more efficient than pigs fed sorghum grain or\ wheat; and pigs fed sorghum grain gained faster and were more efficient than pigs fed wheat, regardless of processing method.Item Open Access Effects of flaked and roasted sorghum grain on finishing swine performance(Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-05-07T21:29:49Z) Allee, G.L.; Hines, Robert H.The value of feeding flaked or roasted sorghum grain to finishing swine (95 to 210 lbs.) was investigated using 54 barrows and gilts. Rate and efficiency of gain for each treatment group were similar. Data from this station indicate that processing methods like flaking or roasting sorghum grain do not improve the performance of finishing swine enough to offset the increased cost of processing.
